Les Miserables by the Death Eaters

Voldemort takes the Death Eaters to see a movie; Les Mis. Then he decides that they will learn the songs and preform the musical. Nagini is transfigured into a human to make up for a lack of girls, and there is much debate over casting (because there isn't enough space in the summary to actually make this sound cool). Just click on the title and trust it will be funny.
